ELECTRICAL CHARACTERISTICS
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: TJ is calculated from the ambient temperature TA and power
dissipation PD according to the following formula:
TJ = TA + (PD)(150°C/W)
Note 3: Some tests are performed under more stringent conditions to
ensure reliable operation over the entire supply voltage range.
Note 4: Digital inputs include: IN1, IN2 and DIODE.
Note 5: IS increases by the same amount as IBSENSE+ + IBSENSE– when
their common mode falls below 5V.
Note 6: Gate turn-on and turn-off times are measured with no inrush
current limiting, i.e., VSENSE = 0V. Gate rise times are measured from 1V to
4.5V and fall times are measured from 4.5V to 1V. Delay times are
measured from the input transition to when the gate voltage has risen or
fallen to 3V. Results are not tested, but guaranteed by design.
